VACUUM CLEANER Filed Aug. 4, 192" 2 Sheets-Sheet 2 jwwmtoz Frank @5012Patented Dec. 24, 1929 UNITED STATES PATENT OFFICE FRANK TYSON, FCANTON, OHIO, AS SIGNOR OF ONE-HALF TO LAWRENCE Gr. IPBITZ, OF

CANTON, OHIO vAcuUM CLEANER Application filed August 4, 1927. Serial No.210,563.

The invention relates to suction cleaners and more particularly to acleaner having 4 ing at different points means for vibrating the carpetbeing cleaned by alternating air currents passing through the nozzle ofthe cleaner.

The object of the improvement is to provide a vacuum cleaner havingmeans for alternately creating air currents through different portionsof the nozzle, whereby the carpet, over which the cleaner is operating,is alternately raised and subjected to vacuum cleanwithin the mouth ofthe nozzle, the carpet being thus rapidly undulated in much the samemanner as would result from shaking the carpet by hand.

The above and other objects may be attained by providing a rotaryvibrator within the nozzle of the cleaner; said vibrator being opentransversely through its center, whereby the induced air current in thenozzle is caused to pass alternately through the open center of thevibrator and around the periphery thereof.

An'embodiment of the invention is illustrated in the accompanyingdrawings, in

which Figure 1 is a bottom plan view of the 1mproved cleaner, showingthe rotary vibrator mounted within the nozzle;

Fig. 2, a detached perspective view of the rotary vibrator Fig. 3, atransverse sectional view through the nozzle, showing the rotaryvibrator in position to cause the induced air current to pass entirelythrough the open center of the vibrator, and I Fig. 4, a similar Viewshowing the rotary vibrator in ,position to cause the induced aircurrent to pass around the periphery of the vibrator as elljflS throughthe open center thereof.

Similar numerals refer to similar parts throughout the drawings.

The improved vacuum cleaner may include the motor ,1, for rotating theusual fan 2, with in the fan chamber 3, in order to create an inducedcurrent of air through the nozzle 4. The mouth 5. of the nozzle. isarranged to have sliding contact with the surface of the its center,

through the central opening carpet, over which the cleaner is operated,indicated at 6.

For the purpose of the invention, theshafiv 7, of the fan, may zle andprovided with a pulley 8.

The rotary vibrator may comprise the shaft 9, journaled in anti-frictionbearings 10, located in opposite end portions of the nozzle.

A pulley 11 may be provided at the central portion of the shaft 9, andoperatively connected to the pulley 8, upon the fan shaft, as by thequarter turned belt 12, whereby the shaft 9 will be continuously rotatedduring the operation of the fan.

The shaft 9 is open transversely through as shown at 13, and at eachside of the center opening, and parallel thereto, is attached a flexiblevane 14, of leather or the like, as by the screws 15.

These vanes are of such width that they will contact with opposite sidesof the nozzle, when the rotary vibrator is in the position shown in Fig.3, and the shaft 9 is so located within the nozzle that one vane willengage the surface of the carpet when the vibrator is turned to theposition shown in Fig. 4c.

In the position shown in Fig. 3, the induced air current will pass upfrom the mouth of the nozzle, entirely through the central opening 13 ofthe shaft, pulling the carpet up into the mouth of the nozzlesubstantially as be extended into .the noz-- air current to pass upwardbetween said vane and the adjacent wall of the nozzle, remainder of thecurrent passes partly of the shaft, and partly upon the other peripheralside thereof.

In this latter position the carpet is held down upon the floor at thepoint of contact with the vane 14, while it is drawn up into the mouthof the nozzle at each side of said point, as illustrated in Fig. 4.

It will be seen that as the vibrator is rotated, the carpet will berapidly undulated, alternating between the positions shown in Figs. 3and 4:, subjecting the carpet to suction while the cleaning as thecarpet is raised and the nap opened. Much the same efl'ect is producedas though the carpet were grasped at one edge and vigorously shaken byhand.

I claim: 1. A vacuum cleaner including suction e means, a cleaningnozzle and a rotary vibrator within the nozzle, said vibrator being open0 transversely through-its center and provided with a pair of oppositelyextending, flexible vanes arranged to intermittently and simultaneouslycontact with'opposite sides of the nozzle, and means for rotating saidvibrator for causing the induced air current in the nozzle toalternately pass through the rotary vibrator and through and around therotary vibrator. v

2. A vacuum cleaner including suction means, a cleaning nozzle and arotary vibrator within the nozzle, said vibrator com prising a shafthaving a transverse opening t'herethrough, a pair of oppositelyextending,

- flexible vanes attached to the shaft and arranged to intermittentlyand simultaneously contact with opposite sides of the nozzle, and. meansfor rotating the shaft for causing the induced air current in'the nozzleto alter-' nateIy pass through the rotary vibrator, and

through and around the rotary vibrator.

3. A vacuum'cleaner including a suction fan, a cleaning nozzle and arotary vibrator within the nozzle, said vibrator including a shaft, apulley intermediate the ends of the shaft, a belt operatively connectingthe pulley with the fan, a transverse opening through the shaft'on eachside of the pulley,and a pair of oppositely extending, flexible vanesattached to the shaft on each side of the pulley 40 and arranged tointermittently and simultaneously contact with'opposite sides of thenozzle, for causing the induced air current in" the nozzle toalternately pass through the rotary vibrator, and through and around therotary vibrator.

In testimony that I claim the above, I have hereunto subscribed my name.

FRANK TYSON.
